SAFE.

EEPECIPICATION forming part of Letters Patent No. 307,937, dated November 11, 1884:.

Application filed May 15, 1884.

To all whom it may concern.-

Be it known that I, J. Ross GROVE, of York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Safes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to safes, the object being to provide a safe with a novel locking mechanism and with a sliding door.

The invention consists in the combination,

with a safe and a hinged door, of a sliding door arranged within the safe, and means for connecting said doors.

The invention further consists in the combination, with a hinged safe-door provided with projecting wedges, of a sliding door arranged within the safe, and formed with grooves to receive said wedges.

The invention further consists in the combination, with a door sliding in Ways within a safe, ofa worm and a screw-rod for opening and closing the door.

The invention further consists in the combination, with a sliding safe-door, of a looking device consisting of a worm and a threepart screw-rod for operating the worm, and

bolt mechanism for separating the parts of the screw-rod.

The invention further consists in the features of construction and combinations of parts hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 illustrates a perspective View of a safeembodying my improvements. Fig. 2 is a section 011 the line as w of Fig. 1 looking toward the front of the safe. Fig. 3 is a vertical section showing the locking devices. Fig. 4 is a sectional detail view. Fig. 5 illustrates a modification, and Figs. 6, 7 8, and 9 illustrate parts detached.

A represents a safe of the usual rectangular form and provided with a hinged door, B. This door is transversely recessed to form dovetail grooves 1), into which are driven wedge-bars O of double dovetail form, as shown in Figs. 1 and 2.

D D represent cleats arranged within the (No model.)

I safe and forming, in connection with the safefront, ways to receive a sliding door, E,which is formed with dovetail grooves d, to receive the wedge-bars C of the hinged door.

F represents aworm-shaft extending through a bearing, f, formed in a block, G, rigidly secured to the inner side of the sliding door E. This bearing f is internally threaded. The shaft F also passes through a bearing, h, formed in an arm or bracket, H, projecting from the front of the safe. This bearing h has a smooth bore, and that portion of the shaft which rests therein is not threaded, but is free to turn within the bearing.

I represents a socket secured to one end of the safe to receive a spindle,.i, formed on the end of the shaft F.

J represents ascrew whose inner end meshes with the shaft F. This rod consists of three parts, viz: an. inner end portion, K, threaded to mesh with the shaft F, and supported in a bearing, 70, formed in the depending end of a bracket, L, secured to the front of the safe, and in a bracket-bearing, 70, secured to the end of the safe, a central portion, K, which is not threaded, and is supported in a sleeve, M, rigidly secured to the end of a lock-bolt, N, and an outer end portion, K extending through an opening in the front of the safe and provided with a hand-wheel, 0. These three parts K, K, and K forming the screw- The outer end of the part K and the inner end of the part K are each formed with a rethe central part, K, is formed with a lug, Z. These lugs rest in the recesses Z Z, thus enabling the entire rod to be turned by the handwheel 0 to operate the shaft F.

As already described, the sleeve M, which receives the central portion, K, of the rod, is rigidly secured to the bolt N. This bolt and its mechanism are provided with the usual casing, N, and may be of any preferred construction to effect various combinations.

It will be apparent that when the bolt N is raised, as shown in Fig. 4, the sleeve will be elevated, thus lifting the central part, K, of the rod J out of connection with the remaining parts of the rod. In thus raising the central part, K, of the rod the latter would be cess,l, on their upper sides, and each end of rod J, are connected in the following manner:

, and K of the rod being applied directly to liable to turn within the sleeve while in its elevated position, and thus fail to connect with the other parts when lowered. To avoid that difficulty I have provided a forked arm, 1?, depending from the bracket L. The forks p of this arm enter a slot, 1', formed on the upper side of the sleeve M, and recesses s,formed on opposite sides of the part K of the rod, to register with the slot 7". Thus when the sleeve M is raised,the forked arm embraces the part K and prevents its turning, so that when lowered its end lugs will enter the recesses of the other two parts of the rod J. The inner portion, K, of the rod is also held by a forked arm, 1?, secured to the sleeve M. The outer end of the part K is recessed to receive the forks of the arm P when the bolt is raised. The outer part, K of the rod J is formed with the ordinary arbor,Q,to prevent its withdrawal.

The operation of the mechanism thus described is as follows: To lock the safe, the hinged door isfirst closed. The rod J is then turned to revolve the shaft F, thus sliding the door E, whose grooves 4 receive the wedge-bars O of the hinged door. When the door E is slid fully into place, the bolt N is operated by means of the usual knob, R, to raise the sleeve M, thus throwing the parts of the screw-rod out of connection and preventing the opening of the doors.

To unlock the safe, it is only necessary to lower the sleeve M by dropping the bolt, (which, as above suggested, is to be controlled by ac0mbination,) and to open the sliding door by the rod J.

I11 Fig. 5 I have illustrated a modification. In that instance the shaft F terminates at the bearing h, and the inner end, K, of the rod J is dispensed with, the sleeve M and parts K the shaft F. This construction will necessitate the location of the bolt-casing and its dial, as well as the outer end of the rod J, at the end of the safe. I do not, however, limit myself to the precise construction herein shown and described, as my invention comprehends, broadly, the use in a safe of a sliding door when combined with a hinged door, and means for securing the two doors together. I therefore reserve the right to make all such departures in form and construction as may properly fall within the scope of my invention.

It is obvious that my improvements are applicable to vaults as well as to safes of various kinds.

' Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with asafe, of a hinged door and a sliding door and means for securing said doors together, substantially as set forth.

2. The combination, with a safe, of ahinged door formed with dovetailed transverse wedgebars, and a sliding door formed with grooves to receive said bars, substantially as set forth.

3. The combination,with asliding safe-door, of a worm-shaft and a threepart operatingscrew for sliding said door, substantially asset forth.

4. The combination,with a sliding safe-door, of a worm-shaft and a screw-threaded block, through which the latter extends,a three-part screw-rod, and means for throwing the parts of said rod out of connection, substantially as set forth.

5. The combination, with a locking-bolt, of a rod composed of sections, a sleeve secured to said bolt and adaptedto support one section of said rod, so that said section may be moved out of connection with the other parts of the rod, substantially as set forth.

6. The combination,with asliding door and a worm-shaft, of a screw-rod joined by lugs and recesses, as described, a sleeve secured to a locking-bolt, and means for preventing the turning of the central part of the rod within the sleeve, substantially as set forth.

7. In a safe, the combination,with a sliding door, of a worm-shaft supported in bearings within the safe, a three-part screw-rod for opening and closing said door, and supported in bearings, as described, a hand-wheel for turning said rod, and abolt for throwing the parts of said rod into and out of connection, substantially at set forth.

8. The combination,with the three-part rod and its slotted sleeve, of a bracket-bearing and a depending forked arm, as and for the purpose set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
